“A right delayed is a right denied.”

“Science investigates, religion interprets. Science gives man knowledge which is power, religion gives man wisdom which is control. Science deals mainly with facts, religion deals with values. The two are not rivals. They are complementary. Science keeps religion from sinking into the valley of crippling irrationalism and paralysing obscurantism. Religion prevents science from falling into the marsh of obsolete materialism and moral nihilism.”

“Use me, God. Show me how to take who I am, who I want to be, and what I can do, and use it for a purpose greater than myself.”

“The church must be reminded that it is not the master or the servant of the state, but rather the conscience of the state. It must be the guide and the critic of the state, and never its tool. If the church does not recapture its prophetic zeal, it will become an irrelevant social club without moral or spiritual authority.”

“On some positions, Cowardice asks the question, “Is it safe?” Expediency asks the question, “Is it politic?” And Vanity comes along and asks the question, “Is it popular?” But Conscience asks the question, “Is it right?”... The ultimate measure of a man is not where he stands in moments of convenience, but where he stands in moments of challenge, moments of great crisis and controversy.”

“Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness.”

“The mere fact that we live in the United States means that we are caught in a network of inescapable mutuality. Therefore, no American can afford to be apathetic about the problem of racial justice. It is a problem that meets every man at his front door. The racial problem will be solved in America to the degree that every American considers himself personally confronted with it. Whether one lives in the heart of the Deep South or on the periphery of the North, the problem of injustice is his problem; it is his problem because it is America’s problem.”

“The arc of the moral universe is long, but it bends towards justice.”

“Let no man pull you so low as to hate him.”

“If a man hasn’t found something he will die for, he isn’t fit to live.”

“We must come to see that the end we seek is a society at peace with itself, a society that can live with its conscience.”

“We should never forget that everything Adolph Hitler did in Germany was "legal" and everything the Hungarian freedom fighers did in Hungary was "illegal." It was "illegal" to aid and comfort a Jew in Hitler's Germany.”

“I have consistently preached that nonviolence demands that the means we use must be as pure as the ends we seek.”

“He who passively accepts evil is as much involved in it as he who helps to perpetrate it.”

“Something is happening in Memphis; something is happening in our world. And you know, if I were standing at the beginning of time, with the possibility of taking a kind of general and panoramic view of the whole of human history up to now, and the Almighty said to me, "Martin Luther King, which age would you like to live in?" I would take my mental flight by Egypt and I would watch God's children in their magnificent trek from the dark dungeons of Egypt through, or rather across the Red Sea, through the wilderness on toward the promised land. And in spite of its magnificence, I wouldn't stop there. I would move on by Greece and take my mind to Mount Olympus. And I would see Plato, Aristotle, Socrates, Euripides and Aristophanes assembled around the Parthenon. And I would watch them around the Parthenon as they discussed the great and eternal issues of reality. But I wouldn't stop there. I would go on, even to the great heyday of the Roman Empire. And I would see developments around there, through various emperors and leaders. But I wouldn't stop there. I would even come up to the day of the Renaissance, and get a quick picture of all that the Renaissance did for the cultural and aesthetic life of man. But I wouldn't stop there. I would even go by the way that the man for whom I am named had his habitat. And I would watch Martin Luther as he tacked his ninety-five theses on the door at the church of Wittenberg. But I wouldn't stop there. I would come on up even to 1863, and watch a vacillating President by the name of Abraham Lincoln finally come to the conclusion that he had to sign the Emancipation Proclamation. But I wouldn't stop there. I would even come up to the early thirties, and see a man grappling with the problems of the bankruptcy of his nation. And come with an eloquent cry that we have nothing to fear but "fear itself." But I wouldn't stop there.”
